Purpose

• The lights-on reminder warning alarm notifies the driver that the TNS and headlights are not turned off.

Function

• The instrument cluster receives the following vehicle condition signals via the CAN signal from the start stop unit and rear body control module (RBCM).

• TNS switch ON signal from start stop unit (TNS and headlights illuminate)

• Driver's front door latch switch ON signal and auto light OFF system OFF signal from rear body control module (RBCM)

• If the ignition is switched to OFF or ACC when all the above vehicle condition signals are received, the instrument cluster operates the lights-on reminder alarm.

• The lights-on reminder warning alarm sound pattern is as shown in the figure.

  

• The Type A instrument cluster operates the lights-on reminder warning alarm and displays a message in the LCD simultaneously.

  

Construction

• The lights-on reminder warning alarm sounds using the buzzer built into the instrument cluster.
